Good seaboat, rides out heavy weather easily

If you want to stay about 4000t, in a longer hull, reduce the beam, that should also help you gaining a bit of speed, however at the cost of some seakeeping.

And you should try reaching at least 31-32 knots of max speed, otherwise this little cruiser won´t be able to outrun many of the heavier cruisers that would torn her apart.

Your sheme gives no idea if it would be possible to place some guns above others. And it also lacks any information about superstructure and funnels.

I agree with the others that drawing her is the ultimate solution to get an idea of deckspace available. Right now I think you´ll run out of it before you´ve placed all your guns.

Reducing draught but increasing length is what I would try to do. Most likely you also have to skip two of your 4,3" guns as there won´t be enough deckspace to allow good arcs to all weapons and TTs anyway and you´ll be able to buy more hull-strength. You know, there should be some kind of splinter protection for your boilers - at least.

What´s the idea behind her CT while there is little armor elsewhere?

Right now she´s a thread to most CLs of WW1 vintage - at least to those afloat around South America and in the southern Pacific but she won´t be able to catch any destroyers or stand a chance against any post-1918 CL. My opinion of course and lucky shots aside...

However, she has good range and I like her just because she´s so different from all the ahead-of-their-era cruisers we see in WesWorld now and then...

Keep it coming,

HoOmAn

Finally there is an issue that is not addressed in StringStyle...the length of the barrels used. There is some difference between a 5"/38 cal and a 5"/51 cal. The same with a 12"/35 cal and a 12"/50 cal. For example: United States (in WesWorld), while restricted to 15 inch and below, would keep the 14 inch around, even though they have perfected a 16 inch type (two actually) and began work on a 18 inch gun. They could of course reline the barrels and get a longer thinker barrel wall with 14 inch diameter. Might give them a longer range, longer barrel life, and might be the start of the super-heavy rounds the American were fond of with the 16"/50 cal on the Iowa.

What I'd do is narrow the beam a tad, and increase the speed. "Good Seaboat" is always nice to have but speed, while not armour , is life for a CL

I've found ships over 29 knots to be difficult with SS. I'd rather have a "Good Seaboat" if I can help it. That will allow the ships to cross the Pacific or slip into the Atlantic past the "Roaring 40s". I might remove some 4.3 inch guns and add a pair of 37mm make them twins.

I'm also working within a length limit. I want to be able to build this class of ships in a Type 1 slip if I can. Might be forced to make her longer, but then I have to build them in the Type 2 slip. I might have mixed up my numbers while I was designing her.

I'll try again, but I was basing the armor off of the existing light cruisers in the fleet (the pre-WWI Nordmark model). Chile is a little behind the style/technology curve, but they plan to make up for it with firepower and range. I should instead design a 1920s proctected cruiser...now that would be different.

Different is what you will get. The cross-sectional is intentionally low, as this is almost a light fast combatant. So 0.91 sounded reasonable give that this is a backward step in technology. A Protected (and not that well either) Cruiser built in the mid-1920s? With 4 single 208mm guns? Well at least she has a speed of 32.25 knots. (not too bad, but not great either...faster than most of my current destroyers).

For normal/large designs we focus on overal hull-strength to be at 1,00 or above while cross-sec hs can be lower. That´s the case with your cruiser so there isn´t any problem. Only for light combatants we agree to focus on cross-sec hs for which we agreed on a minimum of 0,5. Confusing, I know, but you´ll easily get used to it.

However, having a cross-sec hs and overall hs somewhat above 1,00 will allow you some leeway for modifications later during a ships career. That´s interesting especially for those designs that are meant to be different or "behind state-of-the-art" when build.

Well this is the same general design with a cross-sectional of 1.00. Had to add ten feet of length (plus some width and depth) and about 250 tons. Lost some seakeeping, and a touch of steadiness. Gained a whole extra shell hit that this ship could take. Is it worth the trade off so make this ship up to a 1.00 cross-sectional? I'm new at this, so I don't know.

However, just 4 main guns it´s not enough to get a good fire control with the technology of the 20s, as far as I know 6 main guns was the minimal number needed for it, so... what do you need a steady platform for If you can´t get any hits? Why don´t you try a slightly smaller gun?, perhaps 7,5? This gun should still be bigger than the ones in most of the CLs of other navies.
